Which developmental outcome results from the ablation of imaginal discs during larval stages of holometabolous insects?

💡 Explanation

When imaginal discs are ablated, the developmental pathway leading to the formation of adult structures is disrupted because these discs function as precursors to adult organs during pupation, leading to an incomplete metamorphosis. Therefore adult structure formation is inhibited, rather than extended larval state, altered size or insecticide resistance, which would depend on different regulatory mechanisms.
